zookeeper won't close on HBaseTestingUtility.shutdownMiniCluster()

[Elazar Leibovich <el...@gmail.com>]

Running this simple program:

public class Main {
    public static void main(String[] args) throws Exception {
        HBaseTestingUtility utility = new HBaseTestingUtility();
        utility.startMiniCluster();
        utility.shutdownMiniCluster();
    }
}

With the following maven dependencies, full program at
http://pastebin.com/YTW0p1QM :

            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-core</artifactId>

        </dependency>

Cause the following repeated error, the zookeeper instance seems not able
to shut down, full log at http://pastebin.com/HWxady2R

I found similar complaints on the mailing list, eg
http://mail-archives.apache.org/mod_mbox/hbase-user/201205.mbox/%3CA1DB0B51-51A8-4D03-B1DF-F6BA897C3898@gmail.com%3Ehowever
the solution there did not help me.

How can I further debug the problem?

Thanks,
